Flexible laryngoscopes are used for visualizing the larynx, a part of the throat containing the vocal cords. Unlike rigid laryngoscope endoscopes, which have a straight, inflexible design, flexible laryngoscopes have a bendable shaft, allowing them to navigate the curves of the throat more easily. These instruments are commonly used in various medical specialties, including otolaryngology (ENT), anesthesiology, and critical care.
